This is the best tool I have used for installing Adel Clamps. You will be a believer if you try it. I have used it to secure as many as 4 Adels at once. You can see it in action at www.smamtools.com
I have about four or five left more clamps left till I'm done. (for now) I am considering ordering one just for those last few clamps. It sure beats using safety wire to hold them together while your bolting them up. Great idea.
I went to the Tillamook air museum last weekend. They had an old 4330 radial engine on a stand along with the engine mount, intake, exhaust, etc.
What struck me was the way they installed adel clamps. You know how difficult it is to install two adel clamps.
Look at this:
You can see that forty years ago they figured out an easy way to do it. Install the first adel clamp (one is relatively easy) with a full threaded screw, then install a hex nut like an AN315. Now you have a stable platform to attach the other adel clamp and locking nut. Much easier and faster than safety wire, locking clamps, etc.
